Present day automobiles provide for a turn signal flasher deviceembodying a relay. Separately, a buzzer device may be provided atsubstantial extra cost to warn the driver of inadvertence such asignition circuit on, headlights on, or the like.

The invention has for its main object the provision of a relay deviceadapted to serve the dual functions of a flasher unit and a buzzer orinadvertence signal unit.

BRIEF DESCRIPTION OF THE DRAWING The FIGURE of the drawing shows anelectrical schematic of the preferred mode.

DESCRIPTION OF THE EMBODIMENTS The relay Ml embodies a core 11 havingwinding 12, 12a thereon which when energized closes normally opencontacts 13, M, the armature contact M being normally closed withcontact 115.

The flasher circuit for left and right hand turn signal lamps l6, l7embodies the turn signal switch Iii-connecting to normally open contact113 and winding 12a at 19, the winding being connected in parallel fromtenninal 119 with condenser to terminal 211 and through voltage dividingresistor 22 to line 23 connecting positive terminal 24 to armaturecontact 14.

In flasher circuit operation, closure of turn signal switch 18 witheither of turn lamp circuits 16 or 17 energizes winding 12a closingcontacts 13, M completing the lamp circuit for a time period determinedby the time constant of the condenser 20 and winding 12a. Preferably,resistor 22 is of the same resistance as that of winding 12a.

In the buzzer mode of operation normally closed contact 1N5 connectswinding 12 through a control switch 25 by terminal 26 to ground. Thebuzzer control switch 25 may be actuated by conditions such as an opendoor, a key in the ignition in the ON position, or like circumstances ofoperator inadvertence. Closure of switch 25 energizes winding l2efiecting closure of contacts R3, 14 short-circuiting directly toterminal 23 releasing armature contact M to engage contact 15 tocontinue a buzzing action.

A single relay having a normally open and a normally closed set ofcontacts including a common armature with two relay windings thus servesthe utility described wherein several separate buzzer control switches25 connecting to terminal 26 may serve several separate warningrequirements. In such instances a pilot lamp 27 may be connected in eachseparate buzzer warning circuit having its own control switch 25; but asingle buzzer device only is employed.
